WILLIAM C. LANG, vOF CLEVELAND, O1'.[IO.V

FRAME OR HOLDER FOR MOLD-PATTERNS.

To all whom it may concern:

Be it known that I, WILLIAM C. LANG, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have'invented certain new and useful Improvements in Frames or Holders for Mold-Patterns; and I hereby declare the following tobe afull, clear, and exact description of thev invention, such as will enable others skilled in the art to 'which it pertains to make and use the same. This invention relates to an improved pattern-holder more especially adapted for carrying the mold-patterns for forming the faces of both the drag and the cope of a mold, and pertains lmore particularly to a rectangular pattern-holder provided atone of its longitudinal edges with ears adapted to be mounted on a horizontally arranged pivotal rod or member vto the end that the pattern-holder can beswun'g in a vertical plane into a horizontal position in one' direction to receive, at one of'its faces, one of the flask-sections of a' mold, and can be swrmg into a horizontal position in the other direction to receive the other flask-section of said mold at the other of said faces;

Y One object of this invention Yis not only to',v permit the use of plaster or cementitious material in the' formation of the patterns employedinforming the faces of the drag and thev "cope of a mold, but to provide a strongand durable frame'or holder for supporting said pattern-forming material.

Another object is' to minimize the weight and cost of a pattern-holder having the reqfuisite strength and durabilityby forming it oftwo superimposed substantially horizontally arranged metal plates or sections, to provide one of said sections atv its vouter Vface with means instrumental in holding a body of material for forming the pattern employed to form the face of the copeof a mold, and to have the other of said sections provided kat its outer face with means instrumental inholding a-body of material for formingthe pattern employed to form the face of the dragof said mold.

Another object is to have the journalforming ears of the pattern-holder `formed partially on each of said plates.

With these objects-in view,'and to they end of attaining any other advantage herein- `after appearing, this `invention consists in certain features of construction, and combinations and relative arrangement of parts, hereinafter described in this specification,

pointed out in the claims, and illustrated in the accompanying drawings. Y

In said drawings, Figure `1 is aplan view specification@ Letters Patent. Patented Sept. 24, 1918.

' l Application filed April 13, 1916. SerialcNc. 90,967.` y

ofva pattern-holder embodying my invention. Fig. 2- is a vertical section on line 2-'2, Fig. f' l. Fig. 3 is a diagonalverticalsection'on line 3-3,'Fig."l. Fig. 4: is a transverse vertical section on line 4 4, Fig, 2. Fig. 5 is a transverse vertical section showing a portion of the pattern holder illustrated in FigJl supplied with cementitiousl material employed informing patterns.

My improved pattern-holder preferably 'consists of two :substantially rectangular and substantially horizontally varranged superimposed metal plates or .sections A. Said plates lie the-one on or'over the, other and are arranged in substantially parallel planes land removably secured together and form opposite faces respectively of the pat-v tern'holder. Y

One'of the plates Ay is provided'at its outerV facev with means for supporting or holdingat said face Ya body of cementitious material which is to be applied to saidface of-said plate to form the pattern to be em'- ployed in forming the face of the drag Of a mold, and the other of said plates is provided at'its outer face with meansforsup- A porting or holding a body of cementitious material tofbe applied to saidfface of said plate to 'form the pattern to be employed in forming the face of the cope'of saidmold.

Themeans for supporting orholding the cementitious material to be applied to the outer face of each plate 'A preferably comprises shallow compartments 6` Vformed at said face of "said plate byl ribs 7 and, 8 and a marginal rim or flange 9 which areformed on saidplate at the outer face of the plate. The rim or flange 9 of each plate A eXtends along the edges of the plate. The ribs 8 of the plates4 extend longitudinally of the plates, andv the ribs 7 of the plates extend transversely of the plates. VThat is, the ribs 7 and l8 and theflanges 9 of the `plates A form the upright walls of the compartments 6 of the'plates, and each rib of each plate forms a partition between adjacent compartments vof said plate,and it will'be 0bserved that the flanges andthe ribsmaterially reinforce and strengthen the plates.

plate has any side wall thereof which is formed by the rim or flange 9 of the plate undercut, as at l0. The rib or partition formed on each plate between two adjacent compartments is undercut, as at 12, at the inner portions of its sides, and the outer portions of the sides of each rib or partition are beveled, as at 13, and converge toward the outer longitudinal edge of said rib or partition. Preferably the ribs of each plate do not project at the rim or flange of the plate as far from the body of the plate as said rim or flange. Preferably the ribs and the flanges of the plates are so relatively arranged that each compartment formed at the outer face of each plate is arranged directly opposite a compartment formed at the outer face of the other plate, and it will be observed therefore that each rib of each plate is arranged opposite the corresponding rib of the other plate so that each rib of each plate braces or reinforces said plate at a point opposite the corresponding rib of the other plate and so as to render the frame or holder formed by said plates adequately rigid.

Fig. 5 illustrates the application of a body of cementitious material B to each plate, and consequently the compartments shown in Fig. 5 are supplied with a cementitious body for forming patterns, and a metal part b may be partially embedded in said cementitious body if desired andforin a portion of the pattern, as shown at the top in Fig. 5. Fig. 5 shows the undercut portionsy of the flange and ribs of each plate as overlapped by the cementitious body applied to said plate and it will be observed that said undercut portions of said flange and said ribs materially assist in supporting or holding said cementitious body.

It will also be observed that within each compartment of each plate are five screws D which are quincuncially arranged and spaced from the upright walls of said compartment, that said'screws are screwed into said plate, and that said screws have heads arranged to be embedded in the cementitious body to be applied to said plate, as shown in Fig. 5, and forming inwardly facing shoulders (l adapted to materially assist in supporting or holding said body.

Screws G having heads countersunk in the marginal rim or :flange of one of the plates are screwed into the marginal rim or flange of the other of said plates and instrumental in removably securing said plates together.

Screws L having heads countersunk in one of the plates at the intersection of the-longitudinal and transverse ribs of the plates are screwed into the other of said plates and participate in adequatelyisecuring the plates together.

My improved pattern-holder is provided a .one @rie longitudinal edges .wie es a Aadapted to be y, mounted on a horizontally arranged pivotal rod or member (not shown) to the end that the pattern-holder can be swung in a vertical plane into a horizontal position in one direction to receive at one of its faces one of the flask-sections of a mold and can be swung into a horizontal position in the other direction to receive the other flask-section of said mold at the other of said faces. Preferably each ear a is di vided, as at l5, atthe junction of the plates A into two sections and one of said sections is formed on one of said plates and the other of said sections is formed on the other of the plates, as shown in Fig. 4.

1t will of course be understood that modifications may be made in the relative arrangement of the ribs, flanges and contour of my improved pattern-holder without departing from the spirit and purpose of my invention.

VVhatI claim is: -f

A
